EPI 18-20 Polaris Ranger XP Suspension Spring Rear Heavy Duty

Tackle heavier workloads and aggressive terrain without letting rear suspension sag compromise your machine’s handling. The EPI Heavy Duty Rear Suspension Spring is engineered to give your vehicle the extra backbone it needs when factory coils buckle under real-world demands. Delivering a rate roughly 25% heavier than stock, this upgrade actively counteracts the added weight of hard-working accessories—such as full cab enclosures, rear tool setups, winches, and loaded dump beds—restoring lost ground clearance and keeping your chassis level and composed.

• Manufactured from premium chrome silicon alloy steel for exceptional fatigue resistance and long-lasting durability
